Abstract:
This report includes the spectral observations of two unkonwn objects with blue continuum.

ePESSTO+, the advanced Public ESO Spectroscopic Survey for Transient Objects (Smartt et al. 2015 2015A&A...579A..40S), reports the following supernova classifications.

Targets were supplied by the ATLAS survey (Tonry et al. 2018 2018PASP..130f4505T).

Observations were performed on the ESO New Technology Telescope (NTT) at La Silla on the night of 2020 March 21, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution).

The classification spectra and additional details can be obtained from http://www.pessto.org (via WISeREP) and the IAU Transient Name Server.

The classified objects are listed in the Related Objects table below.

Catalog Name Reported RA Reported DEC Reported Obj-Type Reported Redshift Host Name Host Redshift Source Phase (days) Remarks TNS RA TNS DEC TNS Obj-Type TNS Redshift
TNS 2020epc [ATLAS20iaq] 13:44:22.608 -41:25:46.01 Other Blue featureless continuum. No host galaxy detected. Only two points in the light curve at a similar magnitude . 13:44:22.620 -41:25:46.27
TNS 2020epg [ATLAS20iaz] 18:04:35.584 +15:48:00.07 Other Blue featureless continuum. Possibly associated with a faint host. The points in the light curve may indicate a long rise time. 18:04:35.601 +15:47:59.95
